FRUIT-JAR.

QJPEGIFICATION forming part of Letters Patent No. 340,625, dated April 27, 1886.

Application filed November 28, 1884. Serial No. 149,127.

To all whom it may concern.-

Be it known that I, HENRY E. SHAFFER, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Fruit-Jars; and I'do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a plan of a fruit-jar showing my improvement. Fig. 2 is an e1evation,partially in section, of the same. Fi 3 is a bottom view of the clamping-rin Fig. 4 is an elevation of the same, a portion being shown in section. Fig. 5 is a cross-section of the clamping-ring in line or x of Fig. 4. Fig. (Sis a diagram in elevation of the spring and follower, showing a modification.

My improvement relates to that class of fruitjars in which the cover is pressed down on the packing by a clamping-ring that encircles the neck of the jar and holds under lugs blown in the jar.

The invention consists in the'combination of a clamping ring provided with a cross-bar having inclined grooves or ways, a follower consisting of a metallic strip secured across the cross-bar, a spring above the follower, with its ends resting loosely in the grooves or ways, and a pin or bearingacted upon by the spring, passing through the follower and resting on the jar-cover, all as hereinafter described.

In the drawings, A shows the jar, B the cover, and (J the packing, all arranged in the usual way. The jar has two or more lugs, a a, blown in its neck to catch the clampingring, as will be more fully described.

D is the clamping-ring. It consists of the ring proper, b, which encircles the neck of the jar, and a central cross-bar, c, which passes across the top of the jar at some distance above, and is made of the convex form shown. Near the ends of this cross-bar, and on the under side, are made inclined grooves or ways ff, for the ends of the spring to run in, as will presently be described. The cross-bar is also provided with shoulders g g, for the attachment of the ends of the follower.

E is the follower, consisting of a thin strip of metal attached at its ends to the shoulders (X0 model.)

g g by means of rivets h h, cast on the ends of the cross-bar, or by any other suitable means. The rivet-s are shown most clearly in the bottom view of the ring, Fig. 3.

G is the spring, the same also consisting of athin strip of metal placed above the follower, its ends being loose and resting against the inclined waysff.

H is a pin which passes through a hole, k, of the follower, its lower end resting on top of the cover 13, and its upper end being provided with a head, on, that rests between the follower and spring, and a spur, a, that passes up through a hole in the spring, as shown in Fig. 4. A depression is preferably struck down in the follower around the hole It, for seating the head of the pin and to bring the follower and spring as near together as possible.

Instead of the separate pin above described, the spring may be bent down, as shown in Fig. (3, forming a pin, H, said bend passing down through a slot, k, of the follower, and bearing upon the cover.

To seal the jar the ring b is inserted over the neck of the jar and tn rned under the lugs a a, which hold it in place. The ring is provided with offsets p p, which pass over the lugs in inserting, and then by turning the ring it is seated in place. In pushing the ring down the end of the pin H strikes on top of the j ar-covcr, and the further pressure to seat the ring brings the stress of the spring on the pin, and thus the cover rests under constant spring-pressure on the jar.

By the construction above described the clampring and all the attachments are combined together in one device, which can be inserted over the jar together without trouble, thus avoiding the turning of a screw, such as is used in other devices of similar nature. The pressure is uniform at all times, and when the jar cools the spring will follow up and keep the jar tight without additional action, such as is required in ordinary jars.

Having described my invention,what I claim as new, and desire to secure by Letters Patent,

isa In a fruit-jar, the combination of the clamping-ring provided with a cross-bar having inclined grooves or ways, a follower consisting seoszs of a metallic strip secured across the cross-bar, a spring above the follower, with its ends restiug loosely in the grooves or ways, and a pin or hearing acted upon by the spring, passing 5 throughv the follower and resting on the jarcover, as shown and described, and for the In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
